Question

1 studying the properties of acids and bases ( Hcl & NaoH ) on the basis of their reaction with
a) litmus solution (Blue/Red)
b) Zine metal
c) solid sodium carbonate​

Answer 1

Answer:

In the litmus test experiment the blue litmus solution turns to red when hydrochloric is added. Therefore acids such as HCl show acidic character. Hydrochloric acid reacts with active metals such as zinc to form zinc chloride and liberate hydrogen gas. HCl reacts with sodium carbonate to liberate carbon dioxide gas.
